Abstract
While increasing the share of renewable energy to 20% is a challenge for grid
stability, working towards a 100% renewable energy supply requires a
completely new approach. Small island grids are the ideal platform to start
achieving tomorrow’s energy concepts today.
To develop the necessary technologies for a high level renewable energy
island system, Younicos AG built a hardware and software development and test
site in Berlin. The actual system testing shows that the ability to switch off the
diesel generator – i.e. guarantee a stable grid exclusively using fluctuating
sources and batteries and without rotating masses, gives the freedom to choose
any renewable energy configuration between 0 and 100%. Consequently, the
renewable energy system layout can be set up according to the island’s
ecological and economical goals.
A hybrid system with a high renewable penetration can generate substantial
savings by substituting large shares of fuel for electricity generation. Therefore,
in addition to the technological solutions, procedures and business models are
being developed to identify the economic optimal configuration for isolated
systems under a given set of climate and load conditions. The technical
approach, results of the test phase and key parameters of a supply system based
on renewables and storage will be summarized in this paper.
Keywords: island, island energy system, renewable energy, renewable energy
integration, battery storage, grid stability, system optimization.
